WARPING-MACHINE.

To all'whom it may concern:

Be 1t known that I, ARTHUR MURPHY, a

citizen of the United States, residing in Iatl5. This invention relates to warping machines and it consists incertain improvements in such machines having for their principal objects to increase the output of the machine, improve the product, eliminate the necessity for constant attention on the part of the operator in order to assure himself that all of the threads are being continuously advanced, and make it ossible to piece threads with increased facility and convenience whenever they bccome broken.

My invention is fully illustrated in the accompanying drawings, wherein,

Figure 1 is a view in side elevation of the improved machine; Fig. 2 is a view in rear elevation of the reeds and reed frame and mechanism associated therewith; Fig. 3 is a vertical sectional view on the line .ac-m of Fig. 1 and looking rearwardly; Fig. 4 is a view infront elevation, partly in section, showing the means whereby the winding is effected and that part of the stop-motion mechanism which directly affects said winding mechanism; Fig. 5 is a vertical sectional view on a larger scale and taken in a vertical plane immediately to the right of a certain cam shown in Fig. 4t; Fig. G is a top plan view, partly broken away, of what is shown in Fig. 5; Fig. 7 is an enlarged detail view, partly in side elevation and partly in section, of a portion of the mechanism shown in Figs. 2 and 3; and, Figs. S and 9 are detail views illustrating one of the fallers and one of the perforated plates in which they move.

The machine is illustrated in the drawing as designed particularly for the warping of Specification of Letters Patent.

edge warps; it will be understood, however, that the essential features of my invent-ion are applicable to machines desioned for the warping of various other kinds of warps than merely edge-warps. Further, I have only shown in the drawings two beams and their accessory mechanisms; it will be understood that the number of beams and their accessory mechanisms may be increased in a single machine, if desired.

a in the drawings designates a suitable frame and b two tables supported thereon and extending transversely thereof and spaced from each other. These tables are bridged by brackets c in which are journaled a drum or drums el and guide-rollers e and f disposed the one in front of and the other back of said drum; the parts (l, c and f preserve a suitable tension on the warps g, and the drum or drums cl may be connected up in the usual manner with a suitable clock (not shown) to indicate the number of yards of warps passed through the machine.

A rotary shaft h is journaled in suitable bearings 'i under the front table extending transversely of the frame, the table being recessed longitudinally thereof to receive the shaft. This shaft carries a pulley 7' around which a driving belt may be passed and it also carries a gear 7c which projects up through an opening Z in the table b. A pair of brackets m surmount the table b at oppo site sides of the opening Z, and in these brackets is journaled a shaft n carrying a gear o driven from gear by a transmission gear p, also journaled in said brackets; a gear casing g is shown in section in Fig. 4. The shaft n carries the clutch members 1', which are splined thereto, said clutch members being controlled by the levers s pivoted in arms t of the brackets m. A face plate u is fixed on each end of the shaft a, and it has a clutch member u adapted to interlock with the clutch member fr. At each side of the brackets m is another bracket w rendered adjustable to and from the brackets m by a wing-nut w. Each bracket fw has an open recess y forming a bearing for one trunnion of a beam e, the other trunnion of which may be inserted into a socket (not shown) in the clutch member c, the beam being caused to rotate with the face plate u by a pin or the like 1.

In View of the forego-ing it will be seen that the gear o transmits rotary motion to two beams, and that either of these beams is disconnectively connected with the shaft a carrying said gear. The shaft /L continuously rotates, vand so long as the clutch -members r stand engaged with clutch members o, the beams e will be driven; occasionally, however, a thread will break, making it necessary to stop fthe rotation of the parof the-reed frame project arms 8 whichh carry a fallerebox 9; as shown in Figs. 2, 3 and 7, -this box comprises front and kback-walls 10, end walls 11', verticalstrips 12 secured to the frontand back ofzthe box and projecting downwardly, and perforated plates 13 and 14, the former secured directly tothe lower portionof-the -box andfthe latter carried at `the lowerl ends of'the strips v12. Surmount-- ing each wall 10 of the box, and he'ld'thereon by cap-pieces 15,1 are the spaced glass bars 16, over whiclithe `threads g extend `on ltheir-way to-'the beamsthrough the reeds 7 and 2 fand under `rollers e and f and Yover 'drums d.

-In thefperforatedplates 13 and 14 move vertically 1 the' inverted U-shaped fallers 17 eachf-faller being a piece of :bent wire' whose legs Ypenetrate two holes in each plate (so as whose extremities isbent off as l@at 18for a purpose *to be findicated. vThe fallers are held'suspendedlby thethreads-in the position shown'in full lines iliFig. 7.

To the front of the reed frame are secured the brackets 19 land in these are fulcrumed the lever-'structures 20. lil-ach oflthe latter comprises 1an arbor 421 journaled in the brackets 19 andV formed with a cam'22;=two

wvires 23 'projecting rearwardly 'and carry- 4ing a slatr 24 arranged under thefallers, and

two `other wires V25 projectingrea-rwardly at an incline Vand carrying an adjustable weight 26. This weight is so adjusted that `the Vslat24 will be retained in vitshorizontal position,`that is, incontact with a stop 23a dependingifromthe'reed'frame, so long as-the weight ofI a faller orffallers.y is notimposecl upon it; otherwise it is forced rinto the position shown by dotted lines in Fig. 7. In each bracket 19 is also fulcrumed a detent device 27 comprising an arbor 28 carrying a hook 29 having the rearwardly and upwardly projecting arms 30 and 31, the arm 31 being engageable by the cam 22.

Suspended from the reed frame in alinement with the hooks 29, are the vertically slotted guides 32, the length of the slot in each being rendered adjustable by plates 33 having vertical' slots 34 and secured to the guide by the screws 35 Ipenetrating their slots. Each guide is penetrated by a lever 36 which is Vfulcrumedfin a bracket 37 Ain such manner that a relatively small portion fof the length thereof is forward of its'fulcruni. -At its rear vend each lever carries can upright 3Shaving a hook 39 wherebylthe lever may be suspended from the hook `29 and a projection 40 to engage the arm `30A of hook 29.

In the frame a are fulcrumed bell-'crank levers 41 each having a pin 42 underlying the corresponding lever 36; each lever '41 is connected with anotherbellecrank lever 43 l90 `by a flexible connection 44; and each lever 43 isl connected with a-trea'dle 45 by a `flexi- -ble connection 46.

As will be explained, when a faller dropsA and actuates the leverstructure 20, the cor- -responding lever structure 27 is moved to release lever`-36, andthe latter'acts to dises- `tablishtthe clutch for the'beamcorresponding to it. Tothis end the forward end lof each lever 36 is penetrated by a vertically 2movable'stud 47 having a collar 48 resting on the lever and surmounted-.by a disk' 49. Said studvis guided in the lower one oftwo `superposedplatesO and 51; which bridgean opening 52 formed in the fronttablev bover ylever 36, t-he former being above and se- `cured vdirectly against the table and the'latter being below and secured to lthe Linder sideof ytheta'ble with the interposi-tion of spacers 53. The plate 51 is formed withlre- =cessed uprights 54 in whichslides thefshank 55-of a'U-shaped strap 56 receiving an eccentric 57 -on the shaftv h, the `shank being kept in place by cap-pieces 58. I In the plates 50 -and 51 is journaled a shaft 59=car rying a crank 60 at its upper end, andi a lcrank 61 which is disposed in a plane below that of `the shank 55. The crank 61 pro- `jects over the disk 49 and in it slides vertically a-pin 62 adapted to becreceived by a longitudinal slot 63 inthe shank,- said slot being ywide enough so-that in any position ofthe crank y'the' pin mayfbe received bythe slot when the pin is raised by the disk.

"Eachicrank 60 isso 'arranged withrelation to-'the lower 'end of the corresponding lever sthatfthe movement ofthe crank will actuate the lever to cause it to disestablish the clutch.

The operation is as follows: Should a faller drop, through the breaking ot a thread, the lever structure Q0 will be moved .and its cam 22 will move the detent device lever s and disestablish the clutch. The correspondmg beam now ceases to rotate. As

soon as this is observed, the attendant locates the broken thread by the taller which has dropped, and having pieced the thread the faller will be again held elevated. (The affected faller may be readily raised by the attendant by placing the finger against the bent-ott portion 18 thereof.) The operator now depresses lever 45, causing lever 41 to raise the lever 36. The projection 40 on upright 3S now engages arm 80 ot' the detent 2f) and turns the latter on its t'ulerum, the pressure o't' the arm 31 acting on the cam 22 to reset the lever structure 20 in its horizontal position. It no taller remains resting on the slat 24, as soon as the pressure on the treadle has been released, lever 36 falls and its hook 39 rests on the hook 29; it' a faller should be left resting on the slat 24, lever structure 2O will return toward its dotted line position in Fig. 7 and so throw the hook 29 out of the path of hook 39 so that lever 36 will not be suspended. rIhe operator will thus at once detect that there are one or more additional threads to be pieced. As soon as the lever 36 is restablished in its suspended position, the winding is again started by moving the lever s so that the clutch members will be restablished. It should be noted that lever s will not remain in the position to which it is thus moved unless lever 36 is suspended by the hook 29 and thus allows pin 69. to stand clear of the shoulder 64 on the reciprocating shank 55. The downward movement of lever-structure 20 is preferably limited by a suitable stop 65 attached to guide 32.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is:

l. The combination of the frame, a rotary beam, a rotary driving part for the beam, disconnective connecting means between the beam and said driving part, mechanism controlling said means and comprising a part normally movable in one direction, fathers, a pivoted detent having a hook engaging and normally restraining said part againstmovement, and a lever-structure projecting beneath the fallers and fulcrnmed in the frame, said lever-structure being movable upon the impact ot' a faller therewith into actuating contact with the detent, substantially as described.

2. The combination of the t ame, a rotary beam, a rotary driving part for the beam, disconnective connecting means between the beam and said driving part, mechanism controlling said means and comprising a gravity actuated part, fallers, a pivoted detent having a hook engaging and normally restraining said part against movement, and a leverstructure projecting beneath the iallers and fulerumed in the frame, said lever-structure being movable upon the impact of al taller therewith into actuating contact with the detent, substantially as described.

3. The combination of the frame, a rotary beam, a rotary driving part for the beam, disconnective connecting means between the beam and said driving part, mechanism controlling said means and comprising a part normally movable in one direction, fallers, and nnwehanism t'or controlling the position ot said part comprising a taller-controlled detent, pivoted in the frame and having a hook and an arm projecting in substantially opposite directions therefrom, the hook being adapted to engage said part to restrain the same and the arm being adapted to be engaged by said part and effect the movement of the detent into restraining relation to said art upon resetting the mechanism, substantially as described.

l. In a stop-motion mechanism for a varping machine or the like, the combination of a. frame, fallers, a part normally movable in one direction, and a pivoted detent controlled from the fallers and having a hook and an arm projecting in substantially opposite directions therefrom, the hook being adapted to engage said part to restrain the same and the arm being adapted to be engaged by said part and effect the movement of the detent into restraining relation to said part upon resetting the mechanism, substantially as described.
